- No check valve allows unrestricted flow direction
- New condition ensures reliable first-time installation
- Legend Valve quality backs every connection
Legend Valve PEX adapter
The Legend Valve 115-304NLX is a 3/4 inch thermostatic mixing valve adapter designed for PEX plumbing systems. It connects directly to compatible manifolds without an integrated check valve. This new component suits installers working on potable water distribution or hydronic heating loops.
Fits standard 3/4 inch PEX connections
The adapter joins to 3/4 inch PEX tubing and manifold ports using the indicated TMV interface. Because it ships without a check valve, the fitting frees up the circuit for external flow-control devices or system designs that manage backflow prevention separately. No additional proprietary tools are required beyond standard PEX crimp or expansion equipment.
Handles 3/4 inch flow paths
The 3/4 inch bore accommodates typical residential and light-commercial flow rates for hot and cold blending. The absence of a check valve means the adapter does not restrict reverse flow, so it cannot serve as a backflow preventer on its own. California Proposition 65 warnings apply for chemical exposure.

Questions about this item
What is the sustained-use limit for the 115-304NLX valve in a hot-water system?
The 115-304NLX valve is a thermostatic mixing adapter without an integral check valve, so its practical limit is the temperature and pressure rating of the PEX tubing and fittings you install it with.
How much noise, heat or power does the 115-304NLX generate when running all day?
The 115-304NLX is a passive brass mixing adapter with no moving parts, no electrical connection and no pump, so it produces zero noise, zero electrical heat and consumes no power during continuous operation.
What PEX tubing and crimp tools must I already own to install the 115-304NLX?
You need 3/4-inch PEX tubing compatible with the adapter's barbed ends and the correct crimp or clamp rings plus a calibrated crimp tool for that ring size to make watertight connections.
